Chip news: Superfast Wi-Fi and a new 64-bit CPU

The capabilities of upcoming smartphones and tablets can often be seen in the chipsets that are launching now.

Mobile chip update

Superfast Wi-Fi
Wi-Fi and Bluetooth are strong suits for chipmaker Broadcom, and now the company says it has the industry’s most powerful Wi-Fi chip for mobile devices. The BCM4358 is an 802.11ac 2×2 MIMO (multiple input-multiple output) device that combines Wi-Fi and Bluetooth on a single chip.

Broadcom claims the chipset can support Wi-Fi data speeds of up to 650 megabits per second and says consumers can download content two times faster, stream videos with less buffering and connect to multiple Wi-Fi and Bluetooth devices concurrently (e.g. listen to music while playing a game) without interference issues. The BCM4358 supports Android, Windows and Chrome.

64-bit processing
Imagination Technologies is best known for graphics processors, but the company has had its eye on CPUs ever since it bought MIPS almost two years ago. This week Imagination launched the first 64-bit CPU based on the MIPS architecture, which Imagination says is even more power efficient than the ARM architecture. ARM designs most of the processors used in smartphones and tablets today.

Sixty-four-bit architectures are used to build processors for personal computers, but most mobile applications don’t require that much horsepower. That’s expected to change as tablets and smartphones take on heavier workloads. Apple was the first to put a 64-bit processor into a smartphone, and Intel followed suit in February with its own 64-bit processors for mobile devices, claiming it was faster than Apple’s A7 64-bit chip.
